OIL-BURNER.

Specification of Letters Patent.

Patented May 17, 1921.

Application filed June 2. 1920. Serial N 0. 885,992.

To all whom" it may concern:

Be it known that I, JOHN A. LARSON, a citizen of the United States, and resident of Glendale, in the city of New York, borough of Queens, county of Queens, and State of New York, have invented a new and Improved Oil-Burner, of which the following is a full, clear, and exact description.

My invent-ion relatesto a burner, and more particularly an oil burner, and aims to provide adevice of this nature which may be used with extreme economy and improved results for commercial and house heating purposes.

In connection with certain types of oil burners it is well appreciated that difficult-y' has been experienced in adequately vaporizing the fuel, due to the constantly declining quality of the same.

Also difficulty has been experienced in obtaining an instant response of the apparatus when it was desired to imn'lediately extinguish the flame.

Having these defects in mind, I have now constructed a burner, by means of which primarily, a more desirable flame will be produced in that the volatile fluid will be more readily and thoroughly vaporized by virtue of the fact that the air is introduced in such a manner as to insure that the same will act as a most efficient vehicle for the oil or other volatile fluid used, further insuring an intimate co -mingling. and minute subdividing of the particles forming the fuel mixture.

Reference is had to the attached sheet of drawings as illustrating one practical embodiment of my invention, and in which drawings,

Figure 1 is a side view, partly in section,

Fig. 2 is a plan view of the burner, and

Fig. 3 is a sectional view taken along the lines 33 of Fig. 1.

In these views, the reference numeral 5 indicates the reservoir adapted to contain a volatile fluid which is connected to a feed tank 6 by any suitable means, such as a flexible piece of tubing 7, the feed tank being in turn connected by a similar tubing 8 to the burner.

Contrary to the conventional construction, the feedtank 6 is slidably mounted so that the same is movable in a vertical plane, this being accomplished for a purpose hereinafter more fully set forth, by any suitable means such as a slide 9 formed with a rack 10 into which the teeth of a gear 11 project, this gear being conveniently mounted upon a shaft 12 capable of rotating, which shaft may have a ratchet 13 associated with it, which ratchet cooperates with face through which extends tubes 19 their outer ends projecting into the atmosphere, their inner ends communicating with the interior of the casing 17. Connected with the casing by means of a tube 20, is an air compressor 21, which introduces air under pressure into the casing 17, this air conse quently escaping through the tubes 19. The tube 8.connects with a pipe 22 having one of its ends extending beyond the casing 17, its opposite end projecting through the upper face of the casing, and being conveniently centrally disposed within the burner bowl 18. i

It will now be understood by virtue of the well known law of physics that fluid seeks its own level that by moving the tank 6 upwardly by means of the mechanism pro- 'vided therefor, that a certain portion of the volatile fluid 16 will flow through the tubing 8, pipe 22 and so into the burner bowl 18, this fuel being replenished by virtue of the float valve 15. Upon compressed air being applied by means of the blower 21, in lieu of the natural draft now commonly used, a certain amount of the fluid 16 within the burner bowl will be picked up by the air and will be capable upon ignition of producing a most desirable type of flame.

Obviously it will be appreciated that the more the tank 6 is elevated by the mechanism provided for this purpose. the greater will be the flow of fluid through the tubing 8 into the burner bowl 18. and the higher the fluid will rise within this portion,.thus moving nearer to the upper edges of the tubes 19 and constantly being more readily picked up by the air escaping therefrom. l pon the tank 6 being lowered however, the fluid will feed less rapidly into the burner bowl, and will also occupy a lower plane,

thus moving farther from a point adjacent tubing 8 and return to t e tank 6.

It will be appreciated that danger might exist in this operation of the flame being carried into the tank 6, and with a view of eliminating this danger, the upper end of the pipe 22 is conveniently inclosed by means of a screening or other suitable element 23, and it will readily be understood that by means of this screening that any danger of a flame passing into the pipe 22 is re'cluded.

rom the foregoing it willbe understood that I have constructed a burner'in which the flame may be regulated with that'degree of nicety insuringthe production of the temperature desired, and by means of which a more intense and desirable flame will be produced.

Obviously numerous modifications of structure might be resorted to without in claims.

What I' claim as new is: 4

1. A burner, includingv a bowl, tubes extending through said burner bowl andterminating at a point above the same, a feed pipe having one of its ends projecting through said burner bowl at a centrally lothe least departing scope of my oated 'point within the same, and a screen- 1n enveloping the end of the feed pipe, said screening extending within the burner eating with the interior of the-casing, and the outer atmosphere, a source of compressed air communicating with the interior of said casing, and a feed pipe having its inner end extending through the face of said bowl and terminating at a central oint within the same, said feed pipe being in communication with the tank, and means associated with said feed pipe and within the burner bowl for preventing the passage of flame into'the i e.
